Frequently Asked Questions
How many write/erase cycles can the 25LC1024T-I/SM handle, and how long will stored data remain valid?
The 25LC1024T-I/SM is rated for 1,000,000 write/erase cycles per word and guarantees data retention of 200 years under normal operating conditions. These endurance and retention specifications make it a dependable choice for industrial and automotive applications where configuration data must survive millions of update cycles over the product lifetime without data loss.
At what SPI clock frequency does the 25LC1024T-I/SM operate, and which interfaces does it support?
The 25LC1024T-I/SM supports SPI communication at a maximum clock frequency of 20 MHz, enabling fast read and write operations across its 1 Mbit storage. The SPI interface with standard CS, SCK, SI, and SO signals integrates readily with most microcontrollers and FPGAs, reducing firmware complexity in designs where configuration or calibration data must be stored non-volatilely at high speed.
When is the 25LC1024T-I/SM a better fit for a design than a larger EEPROM like a 2 Mbit variant?
The 25LC1024T-I/SM is the preferred choice when a design requires up to 1 Mbit of non-volatile storage while minimizing cost and power consumption, and the stored data fits within 131,072 bytes. Its SOIJ-8 footprint and 20 MHz SPI interface provide sufficient bandwidth for most configuration and logging tasks, whereas a 2 Mbit device would add unnecessary cost and supply chain complexity to space-constrained IoT or industrial sensor nodes.
